How to Apply a Rebooting Patch (Node)

Apply the patch to one
node in the cluster at a time to keep the cluster itself operational during the patch process. With this procedure, you must first shut down the node and boot it to single-user mode using the boot -sx or b -sxcommand, before applying the patch.

Steps

Before applying the patch, check the Sun Cluster product web page for any special pre- or post-installation instructions.

Become superuser on the node to which you are applying the patch.

List the resource groups and device groups on the node being patched.

# scrgadm -pv
# scstat

Switch all resource groups, resources, and device groups from the node being patched to other cluster members.

# scswitch -S -hnode[,...]

-S

Evacuates all device groups and resource groups from the specified node.

-hnode[,...]

Specifies the node from which you are switching the resource groups and device groups.
